Prior to programmatic advertising, finding space for your advert wasn't a particularly easy process. It was expensive, required a number of moving parts, and on the whole was an inconvenient and unreliable process. Programmatic advertising makes this a thing of the past, by introducing instant efficiency. Whether the request comes through at 2pm on Christmas Day, or from Stoke on a cold, wet Tuesday night - Programmatic doesn't care. It's a system that enables ads to be bought and sold, without the same level of human involvement.
